Description

Technical Field

[0001] This invention relates to the field of balloon tube processing technology, and more specifically, to a balloon tube spraying machine. Background Technology

[0002] The balloon catheter drug coating machine is a special device used to prepare drug coatings for balloon catheters. It uses spraying technology to precisely control the amount of drug applied and the uniformity of the coating, eliminating defects such as pinholes and orange peel. This device can be used for drug coating of various drug-eluting balloon catheters such as coronary balloons and peripheral balloons, and is currently the most widely used drug-eluting balloon device.

[0003] Among the publicly available technical documents, Chinese Patent Publication No. CN219921815U discloses a balloon catheter spraying device. This patent mainly addresses the need to spray drugs onto balloon catheters during their production. Traditional balloon catheter equipment often results in significant drug waste during spraying. This patent describes a spraying device that includes a nozzle connected to the outlet of a drug reservoir, configured to face the balloon catheter. A controller is used to control the output of the extrusion assembly, thereby controlling the amount of drug extruded from the outlet of the drug reservoir per unit time. The balloon catheter spraying device, through the controller, can more precisely control the drug output, thus reducing drug waste. However, this spraying machine still has the following drawbacks.

[0004] When the spraying machine sprays the balloon tubing, the sprayed drug is atomized and sprayed onto the balloon, causing the drug to diffuse into the surrounding tubing. This makes it difficult to accurately deliver the drug to the drug-receiving area of ​​the balloon, resulting in poor drug spraying control. Therefore, a balloon tubing spraying machine is needed. Summary of the Invention

[0005] In order to overcome the above-mentioned defects of the prior art, the present invention provides a balloon pipe spraying machine.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a balloon tube spraying machine, including a spraying machine housing, wherein two symmetrically arranged spraying baffles are provided inside the spraying machine housing, a sleeved sliding plate is fixedly connected to one side of the spraying baffle, and a baffle mechanism is provided on one side of the sleeved sliding plate;

[0007] The baffle mechanism includes a threaded sleeve support block disposed on one side of the sleeve slide plate. A linkage screw is internally threaded into the threaded sleeve support block, and a guide frame plate is connected to the outer wall of the threaded sleeve support block. A servo reduction motor is coaxially driven to one end of the linkage screw. A connecting support block is installed on the outer wall of the sleeve slide plate adjacent to the threaded sleeve support block. A longitudinal distance sensor is installed on one side of the connecting support block. A lateral distance sensor is fixedly connected to one side of the sleeve slide plate near its bottom end. A lateral sensing block is provided on one side of the lateral distance sensor. A calibration component is installed below the spray baffle.

[0008] Preferably, the guide frame plate and the threaded sleeve support block are slidably connected. The inner wall of the guide frame plate and the outer wall of the threaded sleeve support block are both polished. The top of the lateral distance sensor and the top of the lateral sensing block are on the same horizontal line. The connecting support block is fixedly connected to the sleeve slide plate and the longitudinal distance sensor respectively. The inside of the sleeve slide plate is provided with two slidably connected guide slide rods from top to bottom. The two guide slide rods are symmetrically arranged, and one end of each guide slide rod is fixedly connected to one side of the inner wall of the spraying machine housing.

[0009] Using the above technical solution, two servo geared motors are started to drive the linkage screw to rotate inside the guide frame plate. The linkage screw drives the threaded sleeve support block to move along the inside of the guide frame plate under the action of the thread. The threaded sleeve support block drives the sleeve slide plate to move the spray baffle. The sleeve slide plate drives the connecting support block to move the longitudinal distance sensor horizontally. Once the longitudinal distance sensor senses the position of the balloon on the balloon catheter, the sensing data of the longitudinal distance sensor is the same as the longitudinal distance set by the controller, and the drive of the servo geared motor can be stopped. The sleeve slide plate drives the lateral distance sensor to move to the right. The lateral distance sensor can sense the lateral sensing block on another sleeve slide plate. The two spray baffles can accurately block the balloon of a specified length.

[0010] Preferably, the calibration assembly includes a pressure sensor installed below the spray baffle. A concave positioning block is fixedly installed on the outer wall of the pressure sensor. A guide groove is embedded in the top of the concave positioning block. A calibration distance sensor is fixedly connected to the bottom of the concave positioning block. A calibration sensing block is provided on one side of the calibration distance sensor. A linkage rod is fixedly connected to the opposite sides of the two concave positioning blocks. A sleeve rotating rod is welded to one end of the linkage rod. Two hinged sleeves are rotatably connected to the outer wall of the sleeve rotating rod away from the linkage rod. A concave hinge block is welded to the bottom end of the sleeve rotating rod near its middle position. An inclined hinge frame is installed inside the hinged sleeve. A threaded recess is connected to the outer wall of the inclined hinge frame near its bottom end. A transmission screw is threadedly connected to the inside of the threaded recess and located on one side of the inclined hinge frame. A support frame plate is provided on the outer wall of the threaded recess. The bottom end of the transmission screw extends to the bottom of the support frame plate and is coaxially connected to a reduction drive motor. The hinge block, the support frame plate, and the reduction drive motor are all fixedly connected to the sliding plate. The two hinge blocks are symmetrically arranged about the hinge rod. The threaded recess and the concave hinge block are rotatably connected to the inclined hinge frame. The concave hinge block, the inclined hinge frame, and the threaded recess are all made of stainless steel.

[0011] Using the above technical solution, the starting reduction drive motor drives the transmission screw to rotate clockwise inside the support frame plate. The sleeve threaded concave block drives the inclined hinge frame to move the concave hinge block upward. The sleeve rotating rod drives the connecting support rod to rotate upward. The connecting support rod drives the guide groove on the concave positioning block to align with the catheter part of the balloon catheter. The two concave positioning blocks can achieve docking and positioning on both sides of the balloon in the guide groove. When the sleeve sliding plate moves and squeezes the balloon on the balloon catheter, the sleeve sliding plate drives the hinge block to move the connecting support rod to the right. The pressure sensor moves to the right and squeezes the balloon on the left side of the balloon catheter. When the pressure sensor generates N force, the controller shuts off the drive of the servo reduction motor and the calibration distance sensor performs horizontal sensing on the calibration sensing block.

[0012] Preferably, the output of the longitudinal distance sensor is connected to a controller fixedly connected to the housing of the sprayer. A downward pressure cylinder is fixedly connected to the top of the inner wall of the sprayer housing. An atomizing nozzle is fixedly connected to the pushing end of the downward pressure cylinder. An injection assembly is connected to one side of the outer wall of the atomizing nozzle. A rotating coil clamping assembly is provided below the atomizing nozzle. The injection assembly includes an injection linkage tube connected to one side of the outer wall of the atomizing nozzle. The injection linkage tube is fixedly connected to the atomizing nozzle. A threaded connector is fixedly connected to the bottom end of the injection linkage tube. A syringe bracket and a rotating block are arranged sequentially from right to left below the threaded connector. A syringe positioning seat is rotatably connected to the bottom end of the rotating block. A compression screw is rotatably connected inside the syringe positioning seat. One end of the compression screw extends to the outer wall of the syringe positioning seat and is coaxially driven by a reduction compression motor. A compression sleeve block is provided on the outer wall of the compression screw and is slidably connected to the syringe positioning seat. The compression sleeve block and the compression screw are threadedly connected.

[0013] Using the above technical solution, the drug syringe is threadedly connected to the threaded connector. The drug syringe is placed at the top of the syringe positioning seat. By starting the deceleration extrusion motor, the extrusion screw is driven to rotate forward inside the syringe positioning seat. The extrusion sleeve block extrudes the piston rod of the syringe, causing the drug inside the syringe to enter the threaded connector. The injected drug enters the nebulizer nozzle through the injection linkage tube and is sprayed downward by the nebulizer nozzle at the bottom. The downward pressing electric cylinder is activated to drive the nebulizer nozzle to contact the balloon part of the balloon catheter.

[0014] Preferably, the rotary disc clamping assembly includes a balloon conduit disposed below the atomizing nozzle. A three-jaw chuck is installed on the outer wall of the balloon conduit near one end. A drive motor is coaxially connected to one end of the three-jaw chuck. The drive motor is fixedly connected to the housing of the spraying machine. A pressure block is pressed and connected to the upper part of the outer wall of the balloon conduit near the other end. A bearing collar is provided on one side of the pressure block and is rotatably connected to the housing of the spraying machine. An extension line take-up plate is embedded and welded to one side of the inner wall of the bearing collar. Multiple snap-fit ​​silicone blocks are fixedly connected in a circular, equidistant arrangement on the upper inclined surface of the extension line take-up plate.

[0015] Using the above technical solution, one end of the balloon catheter can be clamped by a three-jaw chuck, and the other end of the balloon catheter can be inserted into the gap between the pressure block and the bearing collar. The pressure block clamps and locks the other end of the balloon catheter. The balloon catheter extension cable is inserted into the four snap-fit ​​silicone blocks. The drive motor is started to drive the three-jaw chuck to rotate. The three-jaw chuck drives the balloon catheter, which in turn drives the pressure block to rotate the bearing collar. The bearing collar drives the extension cable winding plate to rotate the four snap-fit ​​silicone blocks, ensuring that the balloon part of the balloon catheter can rotate stably under the two spray baffles.

[0016] The technical effects and advantages of this invention are as follows:

[0017] 1. This invention uses a baffle mechanism to activate two servo reduction motors, which drive a linkage screw to rotate inside a guide frame. The linkage screw drives a threaded sleeve support block to move along the inside of the guide frame under the action of the thread. The sleeve slide moves the spray baffle. A longitudinal distance sensor senses the distance at the position of the balloon catheter until the sensing data of the longitudinal distance sensor is the same as the longitudinal distance set by the controller. A lateral distance sensor can sense the lateral sensing block on another sleeve slide. The two spray baffles can move precisely to the balloon drug-blocking part. Precise positioning is achieved based on the balloon length and longitudinal position of the balloon. The drug will be precisely sprayed onto the balloon catheter, avoiding spraying onto the balloon catheter tube. Precise drug delivery is achieved to the balloon receiving site, improving the accuracy of drug spraying control.

[0018] 2. This invention employs a calibration component to start a deceleration drive motor that drives a transmission screw to rotate clockwise inside a support frame. The threaded concave block moves upward along the guide inside the support frame under the action of the thread. The concave hinge block drives the sleeve rotating rod to rotate on two hinged sleeves. The connecting rod drives the guide groove on the concave positioning block to align with the catheter portion of the balloon catheter. The pressure sensor moves to the right, squeezing the left side of the balloon in the balloon catheter to generate pressure. This precisely calibrates the vertical position between the spray baffle and the balloon in the balloon catheter. A calibration distance sensor senses the calibration sensing block, enabling the balloon position of the balloon catheter to be precisely horizontally blocked by two spray baffles, improving the accuracy of drug application.

[0019] 3. This invention uses a rotating disc clamping assembly to allow one end of the balloon catheter to be clamped by a three-jaw chuck. The balloon catheter extension harness is inserted into four snap-fit ​​silicone blocks, which form a ring to wind up the extension harness. The drive motor is started to rotate the three-jaw chuck, and the balloon catheter causes the pressure block to rotate the bearing ring. The extended catheter section of the balloon catheter can be wound and rotated at a specified position. This allows balloon catheters of different sizes to be stored and then rotated. The catheter section of the balloon catheter is less likely to be damaged by large torque. This ensures that the balloon section of the balloon catheter can be stably rotated and coated with medicine under the two spray baffles, and is less likely to be twisted and damaged, causing deviation in the medicine coating, resulting in more accurate medicine coating.

[0020] Through the interaction of the above-mentioned multiple functions, firstly, the two spray baffles can be precisely moved to the balloon drug-blocking position. Secondly, the pressure sensor moves to the right and squeezes the left side of the balloon in the balloon catheter to generate extrusion force. The calibration distance sensor senses the calibration sensing block. Finally, by ensuring that the balloon part of the balloon catheter can be stably rotated and coated with drugs under the two spray baffles, it is not easy to twist and damage. In summary, it can achieve precise drug spraying on the balloon part of the balloon catheter, improving the accuracy of drug spraying control. The system formed by the three key technologies of the baffle mechanism, the rotating disc clamping assembly, and the injection assembly has revolutionized the balloon or stent spraying process and played a significant role in improving the spraying quality and efficiency of balloons or stents.

[0038] In some embodiments, as shown in the appendix Figure 1As shown, the output of the longitudinal distance sensor 8 is connected to a controller 12 fixedly connected to the sprayer housing 18.

The two servo reduction motors 6 are started to drive the linkage screw 4 to rotate inside the guide frame plate 5. The controller 12 can provide precise control. Then, the drive of the servo reduction motors 6 is turned off by the downward pressure cylinder 13. The downward pressure cylinder 13 is started to drive the atomizing nozzle 14 to contact the balloon part of the balloon conduit 15. The atomizing nozzle 14 realizes the atomization and spraying of medicine to the balloon part of the balloon conduit 15.

[0039] In some embodiments, as shown in the appendix Figure 1-9 As shown, the injection assembly includes an injection linkage tube 37 connected to one side of the outer wall of the atomizing nozzle 14. The injection linkage tube 37 is fixedly connected to the atomizing nozzle 14. The bottom end of the injection linkage tube 37 is fixedly connected to a threaded connector 38.

The outer wall of the compression screw 42 is provided with a compression sleeve block 44 that is slidably connected to the syringe positioning seat 41. The compression sleeve block 44 and the compression screw 42 are threadedly connected.

[0040] In some embodiments, as shown in the appendix Figure 1-6 As shown, the rotating disc clamping assembly includes a balloon conduit 15 disposed below the atomizing nozzle 14. A three-jaw chuck 16 is installed on the outer wall of the balloon conduit 15 near one end. A drive motor 17 is coaxially connected to one end of the three-jaw chuck 16. The drive motor 17 is fixedly connected to the sprayer housing 18. A pressure block 22 is pressed and connected above the outer wall of the balloon conduit 15 near the other end. A bearing collar 19 is provided on one side of the pressure block 22 and is rotatably connected to the sprayer housing 18. An extension line take-up plate 20 is embedded and welded to one side of the inner wall of the bearing collar 19. Multiple snap-fit ​​silicone blocks 21 are fixedly connected to the upper inclined surface of the extension line take-up plate 20 in a circular pattern at equal intervals.

[0041] The working principle of the balloon-shaped pipe spraying machine of this invention is as follows:

[0042] Firstly, during the blocking operation, the length of the balloon is set on the controller 12, and the longitudinal distance sensor 8 is set to sense the longitudinal distance of the balloon. Two servo reduction motors 6 are activated, driving the linkage screw 4 to rotate inside the guide frame plate 5. The linkage screw 4 drives the threaded sleeve support block 3 to move along the inside of the guide frame plate 5 under the action of the thread. The threaded sleeve support block 3 drives the sleeve sliding plate 2 to move the spray baffle 1, shortening the distance between the two sleeve sliding plates 2 and bringing them closer together. The sleeve sliding plate 2 drives the connecting support block 7 to move the longitudinal distance sensor 8 horizontally, thus increasing the longitudinal distance... Sensor 8 senses the distance at the position of the balloon catheter 15. Once the longitudinal distance sensor 8 senses the position of the balloon on the balloon catheter 15, the sensing data of the longitudinal distance sensor 8 is the same as the longitudinal distance set by the controller 12, and the drive of the servo reduction motor 6 is stopped. The sleeve plate 2 drives the lateral distance sensor 9 to move to the right. The lateral distance sensor 9 can sense the lateral sensing block 10 on another sleeve plate 2. The distance between the lateral distance sensor 9 and the lateral sensing block 10 is the length of the balloon. The two spray baffles 1 can accurately block the balloon of a specified length.

[0043] Secondly, during calibration, the present invention starts the reduction drive motor 36 to drive the transmission screw 34 to rotate forward inside the support frame plate 35. The threaded concave block 33 moves upward along the inside of the support frame plate 35 under the action of the thread. At the same time, the threaded concave block 33 drives the inclined hinge frame 32 to move the concave hinge block 31 upward. The concave hinge block 31 drives the sleeve rotating rod 29 to rotate on the two hinge sleeve blocks 30. The two hinge sleeve blocks 30 and the support frame plate 35 are more firmly connected to the sleeve sliding plate 2. The sleeve rotating rod 29 drives the connecting support rod 28 to rotate upward. The connecting support rod 28 drives the guide groove 25 on the concave positioning block 24 to align with the catheter part of the balloon catheter 15. The two concave positioning blocks 24 can be in the guide groove The balloon of the 25 is positioned on both sides. When the sliding plate 2 moves and squeezes the balloon on the balloon catheter 15, the sliding plate 2 drives the hinge block 30 to move the linkage rod 28 to the right. The linkage rod 28 drives the concave positioning block 24 to move the pressure sensor 23 to the right. The pressure sensor 23 moves to the right and squeezes the left side of the balloon of the balloon catheter 15. When the pressure sensor 23 generates a force of 1N, the controller 12 shuts off the drive of the servo reduction motor 6. The calibration distance sensor 26 senses the calibration sensing block 27, which can ensure that the balloon part of the balloon catheter 15 is in a horizontal state when the drug is sprayed. The balloon position of the balloon catheter 15 is accurately blocked horizontally by two spray baffles 1.

[0044] Then, when spraying the drug, the drug syringe is threaded onto the threaded connector 38. The rotating block 40 opens the top arc-shaped gap of the syringe positioning seat 41, and the drug syringe is placed at the top position of the syringe positioning seat 41. The reduction compression motor 43 is activated, driving the compression screw 42 to rotate clockwise inside the syringe positioning seat 41. The compression screw 42 drives the compression sleeve block 44 to move to the right along the inside of the syringe positioning seat 41 under the action of the threads. The compression sleeve block 44 compresses the piston rod of the syringe, allowing the syringe to be used on a person. Similar to an injection, the medication inside the syringe can enter the threaded connector 38, while the syringe holder 39 supports the bottom of the syringe front end. The injected medication enters the atomizing nozzle 14 through the injection linkage tube 37, and is sprayed downwards by the atomizing nozzle at the bottom of the atomizing nozzle 14. At the same time as the downward spray, the downward pressing electric cylinder 13 is activated to drive the atomizing nozzle 14 to contact the balloon part of the balloon catheter 15. The two spray baffles 1 can limit and block the catheters at both ends of the balloon catheter 15 to prevent the medication from being sprayed onto the catheter part of the balloon catheter 15.

[0045] Finally, during rotary spraying, one end of the balloon catheter 15 can be clamped by the three-jaw chuck 16, and the other end of the balloon catheter 15 can be inserted into the gap between the pressure block 22 and the bearing collar 19. By rotating the bolts on the pressure block 22, the pressure block 22 can clamp and lock the other end of the balloon catheter 15. When there is a long wire harness at one end of the balloon catheter 15, the extension wire harness of the balloon catheter 15 is inserted into the four snap-fit ​​silicone blocks 21, and the snap-fit ​​silicone blocks 21 form a ring for winding. Extend the cable harness, start the drive motor 17 to drive the three-jaw chuck 16 to rotate, the three-jaw chuck 16 drives the balloon guide tube 15 to drive the pressure block 22 to drive the bearing collar 19 to rotate, the bearing collar 19 drives the extension cable winding plate 20 to drive the four clamping silicone blocks 21 to rotate, the extended guide tube part of the balloon guide tube 15 can be wound and rotated at the specified position, the guide tube part of the balloon guide tube 15 can follow the rotation, ensuring that the balloon part of the balloon guide tube 15 can rotate stably under the two spray baffles 1, and is not easily twisted or damaged.

[0046] In Example 2:

[0047] As attached Figure 10 As shown, the above is one way to achieve electric transmission. In this solution, two sliding plates 2 can slide on the outer wall of the guide rod 11, thereby moving the spray baffle 1. The two spray baffles 1 are manually blocked on the outer wall of the balloon catheter 15. After adjustment, they are locked and pressed against the outer surface of the guide rod 11 by bolts, which can fix the sliding plates 2 on the outer wall of the guide rod 11. The distance between the two sliding plates 2 can be manually adjusted. Therefore, this technical solution also has the function of manually adjusting the distance between the two sliding plates 2 during implementation.

[0048] All contents not described in detail in the specification are existing technologies known to those skilled in the art, and the model parameters of each electrical appliance are not specifically limited and can be determined using conventional equipment. Electrical control components not mentioned in this technical solution are not shown in the figures because they are existing technologies, and will not be described here.

[0049] The above description is merely a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
